SPECIFICATION forming part of `fletters Patent No. 547,273, datedOctober 1, 1895. l

Application filed July 2, 1895. Serial No. 554,739. (No model.)

To all whom. it may concern.: v

Be it known that I, WILLIAM W. MANGUM, Jr., a citizen of the UnitedStates, residing at Nixon, in the county of Hardin and State ofTennessee, have invented a new and useful Winch, of which the followingis a specification.

My invention relates to Winches, and has for its object to provide asimple and efcient device of the class named in which a uniform motionin the desired direction may be imparted to the drum upon which ahoistingcable is reeled, the motion being imparted thereto by anoscillatory operating-lever.

Further objects and advantages of this invention will appear in thefollowing description, and the'novel features thereof will beparticularly pointed out in the appended claims.

In the drawings, Figure l is a perspective view of a winch constructedin accordance with my invention. Fig. 2 is a plan view of the same. Fig.3 is a longitudinal section. Fig. 4is a transverse section on the line 44 of Fig. 2. Fig. 5 is a detail view of a modified form of operatinglever.

Similar numerals of reference indicate corresponding parts in all thegures of the drawings.

l designatesa frame, in suitable bearings 2 of which aremounted theextremities of a transverse spindle 3. Mounted upon said spindle are thecoaxial operating-reels 4, one of which may be secured to the spindle,the same being capable of free rotation in either direction. Theseoperating-reels carry ratchet-wheels 5, of which the teeth are adaptedto be engaged by pawls 6, carried by an operating-lever 7, said leverbeing fulcrumed upon the spindle between the planes of the ratchetwheelsand the pawls being inclined in opposite directions to agree with theopposite inclination of the teeth of said ratchet-wheels, wherebyrotation in opposite directions is imparted to the operating-reels.Actuatingsprings S are connected to the pawls and normally hold them inoperative relation with the ratchet-wheels, and the free ends of saidpawls are connected by means of cords 9 with releasing-levers 10,fulcrumed upon the opercables and increase the relative speed ofroating-lever within reach of the hand by which the operating-lever isgrasped.

The operating-reels are constructed with laterally-extending hubs,forming counterbalancing drums 11, and upon these drums are reeledweight-cords 12, from which are suspended the counterbalancing-weights13.v The weight-cords are reeled in opposite directions upon thecounterbalancing-drums and are adapted to assist the rotation of theoperating-reels in the direction in which they are turned by thepositive engagement therewith of the pawls carried by theoperating-lever,v for a purpose hereinafter explained.

Mounted in suitable bearings on the frame parallel with the axes of theoperating-reels is a spool 14, to which are attached the extremities ofoperating-cables coiled upon the operating-reels, said operating-cablesbeing reeled in the same direction upon said spool, whereby the rotationof either operating-reel will cause the rotation in a uniform directionof the spool. The endsof the spool are tapered or conical inconstruction, as shown at 15, to prevent displacement of theoperatingtation of the spool as the reeling of the operating-cords uponthe spool progresses. y The spindle of the spool also carries ahoistingdrum 16, upon which is reeled the hoistingcable 17, astop-ratchet 18 being fixed to said spindle and being normally engagedby a stop-pawl 19 to prevent backward rotation. Arranged in operativerelation at oneend with said'stop-pawl is a trip-lever 20, fulcrumedupon the side of the frame and having at the extremity of its short arma pin 2l to engage the stop-lever and elevate it at its free end fromengagement with the stopratchet when thelong arm of said lever isdepressed. The lever 2O is normally held out of engagement with thestop-pawl in a clip or keeper 22, supported bythe frame. At the oppositeend of the spool from the hoistingdrum is a brake-wheel 23, with whichco-operates a brake-lever 24, fulcrumed at one end upon the frame andadapted to be compressed to bear upon the surface of said wheel to checkthe rotation of the hoisting-drum when the stop-pawl 19 has beendisengaged from the ratchet-wheel 18 to allow the object-as, forinstance, a well-bucket-to descend.

This bein gthe construction of the apparatus, the operation thereof isas follows: A swinging or oscillatory motion is imparted to theoperating-lever between the planes of the operating-reels to cause therotation alternately in opposite directions of said reels. During therotation of one of the reels by the direct engagement therewith of oneof the pawls 6 the spool, and hence the hoisting-dru in, are turned toreel the hoisting-cable. This rotation of the spool has the effect oflooseningr the operating-cable which is wound upon the otheroperating-reel; but said second operating-reel is turned to take up thisslack of the operating-cable and thus rotate a distance correspondingwith the first-named operating-reel by means of thecounterbalancing-weight. When the operatinglever is moved in theopposite direction, the previously idle operatingreel receives thepositive movement imparted by the operating-lever, and hence impartsmotion through the operating-cable to the spool, and the first-namedoperat-ing reel is turned to take up the slack by means of its attachedcounterbalancing device.

From the above description it will be seen that the improved winch isadapted for a variety of uses-as, for instance, in connection with wellsand for hoisting objects under other conditions.

In Fig. 5 I have shown a modified form of operating-lever in which thepawls 25 are arranged upon opposite sides of the fulcrumpoint 26, and totheir other extremities are attached the branches 27 of' areleasing-cord 28, passing around a pulley 29, arranged at a pointbetween the pawls, said cord being designed to facilitate thedisengagement of the pawls from the ratchet-wheels when it is desired toallow a hoisted object to return by gravity to its former position.

Various changes in the form, proportion, and the minor details ofconstruction may be resorted to without departing fromthe spirit orsacrificing any of the advantages of this invention.

Having described my invention, what I claim is 1. In a device of theclass described, the

combination with a hoisting drum and cable, a spool fixed to androtatable with said drum, co-axially mounted operating reels having operating cables reeled thereon in opposite directions and attached tosaid spool to reel thereon in the same direction, means for rotatingsaid reels alternately in opposite directions, such means includingratchet-wheels and an operating lever fulcrumed between the planes ofsaid reels and having pawls to alternately engage the ratchet-wheels,andcounterbalancing devices including drums fixed, respectively, to theoperating reels, ropes and counterbalanc` ing Weights, said ropes beingreeled upon the drums to impart motion to the operating reels in thedirection in which said reels are turned by the positive engagementtherewith of the operating lever, whereby the slack of an operatingcable attached to one of the reels during the positive rotation of theother reel is taken up by the counterbalancing device, substantially asspecified.

2. A winch havinga frame, a hoisting drum and cable, a stop-ratchetfixed to the drum, a stop-pawl arranged in operative relation with thestop-ratchet, and a trip-lever fnlcrumed upon the frame and having a pinto engage the stop-pawl to disengage it from the stopratchet, a spoolsecured to and adapted to rotate with the hoisting drum, a brake-wheelcarried by the spindle of the spool, a brakelever co-operating with thebrake-wheel, coaxial operating reels carrying ratchet Wheels, anoperating lever provided with pawls for engaging said ratchet wheels andimparting motion in opposite directions alternately to the operatingreels, operating cables reeled in opposite directions upon the operatingreels and in the same direction upon said spool, and counterbalancingdevices including drums fixed upon the operating reels, and cablesreeled in opposite directions upon said drums and carrying weights,substantially as specified.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two witnesses.
